Chapter 6, Problem 6B.3P

Interpretation Introduction

Interpretation: Under the given conditions, the expression for standard enthalpy of reaction and heat capacity at constant pressure has to be calculated.

Concept introduction: The standard reaction enthalpy is equal to the sum of standard enthalpy of products minus standard enthalpy of reactants.  The heat capacity at constant pressure is the rate of change of enthalpy of formation with temperature.  The relation between equilibrium constant and enthalpy of reaction is,

  $\frac{\text{d}\left(\ln K\right)}{\text{d}\left(\frac{1}{T}\right)}=\frac{-{\Delta }_{\text{f}}{H}^{\text{ο}}}{R}$
